Which of the following is NOT an example of surface fuel?

• A. Grasses
• B. Leaf litter on the ground
• C. Canopy needles
• D. Moss on the ground

Answer: (C)

Fuels are categorized by where they are located, which shapes how a fire behaves. Surface fuels are on or immediately above the ground and include grasses, leaf litter on the forest floor, and moss growing at ground level. These fuels ignite and burn near the ground, driving the rate of spread at the surface.

Canopy needles are located high in the trees, in the crown, not on the ground. They burn as crown or aerial fuels, which can lead to rapid, intense crown fires once the flame front climbs into the canopy. Because of their location, canopy needles are not considered surface fuels.

So the item that is not a surface fuel is the needles found in the tree canopy.
